# Overview

The Coupler.io Public API is a REST API. It covers workspaces, dataflows, datasets, integrations, credentials, templates, and execution data.

Requests use JSON over HTTPS. Paths in this reference are relative to the API host - `https://api.coupler.io`.

Start with `GET /v1/workspaces`. Use a returned workspace `id` as `workspace_id` on the other endpoints.

**Quick start**

1. Open the API access section on the [Coupler.io user profile](https://app.coupler.io/app/profile) and copy the personal API token.
2. Send `Authorization: Bearer <token>` on every request.
3. Call `GET /v1/workspaces` and continue with a workspace id from the response.

```bash
curl "https://api.coupler.io/v1/workspaces" \
  -H "Authorization: Bearer <token>"
```

The organization must be on a plan that includes the public API. Otherwise the API returns 403. See Rate limits for the allowance.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.coupler.io/api/overview.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
